Compared with televisions, monitors have much higher current, power consumption, temperature, resistance to electrical disturbances, ability and margin to withstand electrical attacks, and average unobstructed holding time. At the same time, monitors must also hold a full barrier metal shell to ensure electromagnetic compatibility and disturbance efficiency; In terms of component selection, the components controlled by LCD monitors have higher individual characteristics in terms of voltage resistance, current, temperature, humidity, etc. than those controlled by televisions; In terms of the requirements for the installation and debugging of components and the aging process of the entire machine, the requirements for monitors are also higher. When manufacturing televisions, the aging of the entire machine is usually done by powering on at room temperature for 8 hours on the assembly line, while the aging of the entire monitor must be powered on for more than 24 hours on an aging assembly line with low temperature and high humidity sealed conditions to ensure the fluctuation of the entire machine. The demand for improper and uninterrupted control of components held by the television. If the TV is forcibly held as a monitor, it is easy to cause obstruction, and during busy times, it may cause unexpected disruptions due to the high temperature of the TV's tasks.

Assuming that the degree is determined by the amplitude and frequency characteristics of the video channel, the restoration degree is mainly determined by the phase of the chromaticity and luminance signals of the three primary colors of red (R), green (G), and blue (B) in the LCD monitor. Due to the fact that LCD monitors generally observe audio images, the demand for color restoration of the monitor is higher than that of televisions. Therefore, amateur LCD monitors should have precise compensation circuits and delay circuits in brightness, chromaticity processing, and R, G, and B processing to ensure phase synchronization between the light/color signal and the R, G, and B signals.

The intelligent residual image removal of digital image processing chips follows the continuous monitoring of output signals. Based on the root mean square value of each frame of the output signal, it determines whether the image is still or dynamic. The root mean square value reflects the average brightness level and brightness distribution of the output image. Based on this parameter, we can roughly determine the personality and differences of each frame of the output signal. Assuming that the output image is still for a period of time, the residual image removal engine will be launched in a fragmented manner. This engine will actively move the format of the output signal according to the static or active situation of the output image, so that the output image will undergo small and rapid changes in the position displayed on the screen, lifting the control on the liquid crystal molecules and their own and unchanged state. And regarding the liquid crystal molecules The static control voltage is precisely the basic cause of residual images that occur after playing still images on the LCD screen.
